how mass-tech extreme 2000 works
100% whey high-protein shake

MASS-TECH EXTREME 2000 delivers more protein per serving than most other mass gainers available on the market. With a whopping 80g of premium protein (when mixed with 16 oz. of skim milk), your body will have all the building blocks it needs to build the size and muscle you're looking for.*

In addition, unlike many other mass gainer formulas, MASS-TECH EXTREME 2000 contains only high-quality, milk-derived protein sources with the highest biological value.

Only High Biological Value Protein Sources.

MASS-TECH EXTREME 2000 supplies over 400g of carbohydrates (when mixed with 16 oz. of skim milk) through a multi-phase carb complex to spike your insulin levels within normal ranges and promote muscle glycogen replenishment. This will help creatine reach your muscles and put your body in an extreme anabolic state.*


The new, scientifically superior MASS-TECH EXTREME 2000 formula delivers a massive 2,000 calories (when mixed with 16 oz. of skim milk) and delivers high-quality whey protein and easy-to-digest complex carbohydrates.

In a university study, subjects consuming 2,000 calories in addition to a high-protein diet and a weightlifting program gained 6.8 lbs. of mass (vs. 1.3 lbs. in the control group).* This formula is so powerful you only need one serving a day!

Rozenek et al., 2002. Journal of Sports Medicine and Physical Fitness. 42(3):340-7.


Unlike our competitors that contain little to no creatine, MASS-TECH EXTREME 2000 contains a clinically validated 10g dose of creatine to help you increase strength and regenerate ATP stores that are reduced during resistance training.* In a human clinical study, subjects gained 6 lbs. in just 6 weeks while using the same creatine dose found in MASS-TECH EXTREME 2000.*

Buford et al., 2007. Journal of the International Society of Sports Nutrition. 4:6.


Each serving of MASS-TECH EXTREME 2000 (when mixed with 16 oz. of skim milk) delivers 17.2g of BCAAs including 8g of musclebuilding L-leucine. L-leucine is a powerful nutrient signaler that enhances mTOR activation and causes amplified protein synthesis. In a clinical study, L-leucine was shown to help subjects increase their 5-rep max strength by over 40% in just 12 weeks.* What's more, when mixed with 16 oz. of skim milk you get 13.8g of L-glutamine and precursor to support muscle recovery.* You won't find this amount of aminos in any other mass gainer on the market!

based on research at a leading american university

In an 8-week study, subjects consuming a high-protein diet containing approximately 2,300 calories and performing a weightlifting program added 2,000 calories to their regimen. The results were examined and, on average, subjects gained 6.8 lbs. of mass while control subjects gained 1.3lbs.*

Calling this stuff terrible is a compliment. Ill be surprised if I finish the bucket

Jun 30, 2020

Disgusting. I’m usually not too picky when it comes to taste but this was by far the worst tasting protein powder I’ve ever tasted. I’m trying to figure out if this was intended to taste like this or this batch somehow went bad. Do not buy this product.

Does what it says. I've always been underweight my entire life and no matter what I ate I never put on any weight. After having this I gained 9 pounds in two weeks. The only downside is it takes 3 shakers worth for the whole daily dose and it's so thick that you have to spend 5 minutes shaking it to mix it so I use a blender.

Awesome results. Gain mass and strength. But don't mix well. You need blender to mix it.

Do not buy. The flavor is rancid, it’s sticky and gooey like drinking a big cup of snot. It’s impossible to shake in a shaker so have your blender close by. Immediately after drinking it’s a super heavy feeling in your stomach, making it feel like you’re going to throw up constantly for the next couple hours. I had an awful experience, would never recommend to my worst enemy.

I was looking for a reasonably priced weight gainer and saw this on sale, so I figured 22 pounds should be great. I was wrong. The taste is not good. It doesn't taste anything like chocolate or brownie, let alone triple chocolate brownie. It's like a watered down imposter chocolate that failed to make it past the test phase. Mixibility isn't great either, as you'll probably have to shake for about 5 minutes straight to get rid of the persistent little clumps that form. The serving size isn't bad but there's no way you'll fit that in one normal shaker bottle if you plan on adding water or milk. Even with my 45 ounce shaker bottle, I can only add about 20 ounces of water with half the serving size in order for a decent consistency. Overall, I'm not pleased with this and won't buy it again regardless of sale price. I can't imagine the vanilla flavor is any better. If you want a weight gainer, find something with better quality even if it's more expensive.

Taste good, and mixes well. Not to mention that I don’t need a pre-work our with this one.

Triple chocolate brownie tastes like vanilla and is way to sweet. But my biggest issue with the product is it is impossible to mix. You literally have to eat the shake rather than drink it.

Impossible to open, you get what you pay for. I researched all gainers and this is the best value you can get when it's on sale. Taste and mixability aren't the best, but you get what you pay for. Only 1 or 2 scoops are able to be mixed at a time unless you blend it all and chug it down
